Charging device with stress stored by charging that is initiated by externally applied force, and that being eventually released by heat due to charging saturation

ABSTRACT

A secondary cell featuring transient rise in temp. once charged to saturation, to be coupled and thereby forming a composite structure with a charging assembly by mutual engagement of conductive contacts provided on either part, the force of union generated by the coupling will compress a thermosetting prestressed means which is a spring or otherwise prestressed element while the coupling brings the contacts into conduction by which the charging is initiated, the momentum prestressed thereby will be released once charging in the secondary cell reaches its saturation, and that followed by cutoff of the charging current to the secondary cell.

BACKGROUND OF THE INVENTION

[0001] Along with booming development of hand-held type or portable electric appliances or utilities secondary rechargeable batteries or cells are finding ever more extensive applications from day to day, that being the background, the present invention relates to an embodiment comprising a charging assembly and a secondary battery set to be mounted therein and being matched therewith, characterized with transient temperature rise in response to a charging saturation, such as, for example, a nickel/cadmium, a nickel/hydrogen, a nickel/zinc, or a ferrous nickel cell, executed in a specific configuration, both parts being furnished with conductive contacts to facilitate transfer of electric power to each other, once force is applied thereto, a spring will be compressed to store stress, meantime contacts are brought into conduction to initiate a charging cycle, stress stored in the spring will be released by control of both the saturation testing device and the interfacing matched thereto, whereby contacts binding the secondary cell and the charging assembly are undone, the undoing may be made with respect only to the secondary battery cell, or only to the charging assembly, or still only to conductive contacts inside the charging assembly, so that charging current in the secondary cell is cut off altogether; said saturation testing device comprising: temperature sensor to test the rise in temperature when the cell charging reaches its saturation, and that in turn serving to determine the timing to cut off charging once saturation is reached, or alternatively a temperature testing means may be provided with conductive contacts in the charging assembly, so that the battery cell is secured in place when inserted into the charging assembly and a stable conduction is made way between the entire charging assembly and the cell, so that charging may occur with respect to the cell alright, in the meantime, the temperature sensor is maintained in a set status under test until when saturation occurs on the cell that is being charged, cell going through a rise in temperature to bring the temperature sensor to a respondent reaction, whereby the charging assembly and the cell are driven to a on-release, cutoff status, and power supply to the secondary cell is cut off, charging current blocked accordingly.

SUMMARY OF THE INVENTION

[0002] The present invention relates to a combination to specific configuration of a secondary battery cell set characterized with a transient temp. rise when charged to saturation, with a charging assembly which goes with the battery set, both parts being furnished with conductive contacts to transfer power between themselves, by the force prevailing when both are embodied together heat produced by the spring that is being applied at the same time or due to other storage parts is applied to release the prestressed means, conductive contacts are thereby brought into conduction, and a charging cycle is initiated, when charging to the secondary cell reaches saturation, heat will intervene to release the prestressed state whereby conductive contacts on both the secondary cell set and the charging assembly are pushed apart, and charging current theretofore charging to the secondary cell is cut off altogether.

[0083] 7. Having thermosetting memory alloy or binary metal processed into conductive contacts for the charging assembly, meant, in addition to getting coupled to conductive contacts on the secondary cell set, but also for holding the secondary cell set in position, such conductive contacts for the charging assembly, on being heated by saturation of charging of the secondary cell set, will get deformed to release hold of the secondary cell set which will then fall straight off the conductive contact and power supply is blocked forthwith;
